CHANGING THE ORIFICE
Before replacing the orifice, the gas supply and power must be shut off. The HSG200 is shipped from
factory with a #8 - 0.199
” orifice installed and HSG400 is shipped from the factory with a T - 0.358” orifice
installed. The combination gas valve pressure regulator, which has an outlet pressure setting range of
approximately 2.0” w.c. (498.2 Pa) to 4.0” w.c (996.4 Pa) is factory set at 3.5” w.c. (871.85 Pa). The HSG
Series burners come with an orifice kit that contains all the size orifices listed in Figure 11.
To remove the orifice, locate the HSG manifold (Figure 12).
Figure 12: HSG Manifold
Once the HSG manifold is located, remove the slotted orifice cap, making sure the orifice cap gasket stays
attached to the orifice cap and is not damaged (Figure 13).
